riscv's <vdso/processor.h> uses barrier() so it should
#include <asm/barrier.h> to prevent build errors.
Fixes this build error:
CC [M] drivers/net/ethernet/emulex/benet/be_main.o
In file included from ./include/vdso/processor.h:10,
from ./arch/riscv/include/asm/processor.h:11,
from ./include/linux/prefetch.h:15,
from drivers/net/ethernet/emulex/benet/be_main.c:14:
./arch/riscv/include/asm/vdso/processor.h: In function 'cpu_relax':
./arch/riscv/include/asm/vdso/processor.h:14:2: error: implicit declaration of
function 'barrier' [-Werror=implicit-function-declaration]
14 | barrier();
This happens with a total of 5 networking drivers -- they all use
<linux/prefetch.h>.
rv64 allmodconfig now builds cleanly after this patch.
Fixes fallout from:
815f0ddb346c ("include/linux/compiler*.h: make compiler-*.h mutually exclusive")
Fixes: ad5d1122b82f ("riscv: use vDSO common flow to reduce the latency of the
time-related functions")
